Hi,
Unfortunately this is expected.
If you take a snapshot you should not expect a clone but a RBD snapshot.
Please see this BP:
https://blueprints.launchpad.net/nova/+spec/implement-rbd-snapshots-instead-of-qemu-snapshots
A major part of the code is ready, however we missed nova-specs feature

Hey,
Thanks all for your replies. We finished the migration to XFS yesterday morning
and we can see that the load average on our VMs is back to normal.
Our cluster was just a test before scaling with bigger nodes. We don't know yet
how to use the SSDs between journals (as it was recommended)

Hi,
We settled on Samsung pro 840 240GB drives 1½ year ago and we've been happy
so far. We've over-provisioned them a lot (left 120GB unpartitioned).
We have 16x 240GB and 32x 500GB - we've lost 1x 500GB so far.

Hello Christian,
Thank you for your detailed answer!
I have other pre-production environment with 4 Ceph servers, 4 SSD disks
per Ceph server (each Ceph OSD node on the separate SSD disk)
Probably I should move journals to other disks or it is not required in my
case?

Timur,
As far as I know, the latest master has a number of improvements for ssd disks.
If you check the mailing list discussion from a couple of weeks back, you can
see that the latest stable firefly is not that well optimised for ssd drives
and IO is limited. However changes are being made

Hello everyone,
I plan to use CephFS in production with Giant release, knowing it's not
perfectly ready at the moment and using a hot backup.
That said, I'm currently testing CephFS on version 0.80.5.
I have a 7 servers cluster (3 mon, 3 osd, 1 mon), and 30 osd (disks).

Thomas,
Sounds like you're looking for ceph mds remove_data_pool. In
general you would do that *before* removing the pool itself (in more
recent versions we enforce that).
